Interactive group decision making method based on probabilistic hesitant fuzzy similarity(基于概率犹豫模糊相似度的交互式群体决策方法)

open access: yesZhejiang Daxue xuebao. Lixue ban, 2022
概率犹豫模糊集(probabilistic hesitant fuzzy set,PHFS)是犹豫模糊集的推广,在犹豫模糊集基础上通过为每个隶属度添加与之相对应的概率,以全面表达专家赋予的初始决策信息,是处理多属性指标决策问题的一种有效工具。首先,介绍了概率犹豫模糊数(PHFN)的基本定义和相关运算,指出了传统PHFN的得分函数和汉明距离的不足,并给出了改进方法。其次,通过适当补充隶属度集合中的元素数量提出了PHFN的汉明距离和相似度概念,依据专家赋予的评价矩阵引入了概率犹豫模糊矩阵(PHFM)相似度 ...

车辆磁流变半主动悬架混合阻尼模糊电流控制研究 [PDF]

open access: yes, 2018
基于可调Sigmoid力学模型,对磁流变阻尼器(Magnetorheological Damper,MRD)的阻尼动态特性进行辨识拟合,建立1/4车半主动磁流变悬架系统模型。在混合阻尼控制基础上,利用模糊控制器,提出一种混合阻尼模糊电流控制策略,实现对MRD等效阻尼系数的连续可调与阻尼分配系数的自动调节,增加其灵活控制性与自适应性。在此基础上,同时分别在冲击路面与随机路面激励下,将该算法与混合阻尼开关电流控制和被动控制进行仿真对比分析,结果表明所提控制策略具有更好的减振性能。国家自然科学基金项目 ...

基于变权重和组合隶属度函数的GIS气体绝缘状态评估

open access: yesGaoya dianqi, 2021
在GIS气体绝缘状态评估过程中,不同的权重确定和隶属度函数选择方法会导致评价结果的不同,进而影响评价结果的准确性。为了避免主观因素的影响,文中在利用熵权法确定权重的基础上,根据变权综合理论引入均衡函数来调整各评价指标的权重。此外,采用梯形、Γ形以及k次抛物线型相结合来确定各指标的隶属度函数,以避免单一隶属度函数所造成的评价误差。最后,利用综合诊断模型来确定GIS气体的绝缘状态,并对比常权重和单一隶属度评价结果。实例分析表明,该方法可以准确有效的评估GIS设备气体的绝缘状态。
